LOOM FOR WEAVING TUFT ED FABRICS.

SPECIFICATION forming part of Letters Patent No. 411,410, dated September 17, 1889.

Application filed April 19, 1889. Serial No. 307,821- (No model.)

To ctZZ whom it may concern.-

Be it known that we, HORACE \VYMAN and JONATHAN G. GALE, both of \Vorcester, county of ore-ester, State of Massachusetts, have invented an Improvement in Looms for WVeaving Tufted Fabrics, of which the following description, in connection with the accompan ying drawings, is a specification, like letters on the drawings representing like parts.

United States Patent No. 343,110, dated June 1, 1886, shows and describes a series of carriages made movable in the direction of the length of the warp, they having combined with them tuft-yarn carriers or needles, the movement of the carriages enabling any one of the series of tuft-yarn carriers or needles cooperating with it to beplacedin proper po sition with relation to the warp to enable tufts to be formed from the yarns contained in the said tuft-yarn carriers. In practice it has been found that the ends of the tuft-yarns left projecting beyond or through the said carriers or needles are liable to become en tangled with each other, so that when the carriers or needles are shifted to supply a yarn of another color the yarn end fails to be properly presented to the foundation-warp. To overcome this tangling together of the tuftyarns, as described, we have provided each carriage with a series of pockets, into which the carriers or needles draw all the tuft-yarns to thus separate them one from the other preparatory to selecting and dropping into position the needles which are to furnish yarns for the next row of tufts to be made, this course making it impossible for the yarn in one carrier or needle to catch on and to be held back by the yarn of another carrier or needle, or to take another yarn with it. We have also changed the shape of the carriagethat is, we have made its under edge convex or curved, as such shape has been found in practice to insure more ready movement for the carriages.

The particular feature in which our invention consists will be pointed out in the claims at the end of this specification.

Figure 1 is a partial side elevation of a sufficient portion of a loom of the class referred to in the said patent with our improvement added to enable our invention to be understood. Fig. 2 is a partial right-hand elevation of the devices shown in Fig. 1, especially those devices in which our invention lies. Fig. 3 is an enlarged side elevation of one of our improved carriages with its depending pockets, the dotted lines showing part of a needle in one of the said pockets with the pro j ecting tuft-yarn drawn up therein, while another needle in another pocket is represented as lowered to enable its tuft-yarn to be presented to the foundation-warp. Fig. 4 is a right-hand end elevation of the carriage shown in Fig. 3. Fig. 5 is a top or plan View of the carriage shown in Fig. 3.

Referring to the drawings, the frame-work A, the upright A the leverA, the depending frame 13, and tuft-yarn carriers or needles 0', having tuft-yarns t, are and may be all substantially as in the said patent, wherein like letters are employed to designate like parts.

In Fig. 3 we have only shown parts of two tuft -yarn carriers or needles, they being marked by the letter 0, and in practice it will be understood that the said. tuft-yarn carriers (shown by dotted lines) are and may be of usual construction, there being one such tuftyarn carrier in each pocket a (to be described) of the carriage.

Our improved carriage consists, essentially, of a metal plate or bar a, having soldered or otherwise connected to or forming part of it a series of pockets at, one for each tuft-yarn carrier to be used, the said tuft-yarn carriers, suitably threaded or provided with tuft-yarns in usual manner, being extended into the said pockets, and being guided thereby during the movements of the carriages and of the tuft.

yarn carriers.

By providing the carriage with separate pockets for each tuft-yarn carrier, and into which the latter are drawn when not to present a tuft-yarn to the warp, we are enabled to separate each tuft-yarn from the one next to it and prevent the entanglement of one yarn with the one next to it.

To secure better n'ioveme'nt for the carriages,we have curved them at their under sides, the curve being struck substantially from the center 13 of motion of the depending frame 19 on the lever A.

In Figs. 1 and 2 We have shown but one earriage mounted upon the bars 109, forming part of the depending frame 19; but it Will be understood that there will be as many car riages on the said bars as there are tufts in each row of tufts.

We claim- 1. The combination, with the supporting bars and the carriages guided by the said bars and provided with a series of pockets, of the tuft-yarn carriers in the said pockets, substantially as described.

2. The combination, with the supporting-
